General pattern making

The results obtained are consistent with the existing views on the tendency of polyconjugated systems towards spontaneous stabilization upon thermal treatment heating makes the system more resistant to thermal degradation. TGA curves (Fig. 4.2) of the samples subjected to thermal treatment at 200 and 350°C are shifted to higher temperatures, with retention of the general pattern of weight loss. Thus, the carbon-rich structures were formed at relatively low temperatures. 

At Stage I conceptual surveys are carried out in order to prepare the conceptual design. The particular objective is to identify the general pattern of the geotechnical conditions for the pipeline construction internationally, in a country or within a certain region, and to make estimation of their possible change in order to select and to make an optimal option for a 10 km wide corridor of interest. 

The general pattern of this spectrum, however, makes its first order character questionable. Thus, we recorded the 31P, 13C and H spectra on a Brucker WH 250 instrument. The 31P spectrum then appeared as a real first order one with the following figures doublet at 23.64 and 23.24 ppm, triplet at 12.95,12.55and 12.16ppm, J(P—P) = 40.28 Hz. These spectra clearly support the assumed structure for the final product as revealed by mass spectrometry. 

In all proton transfer reactions, the electron-rich base donates an electron pair to the acid, which usually has a polar H—A bond. Thus, the H of the acid bears a partial positive charge, making it electron deficient. This is the first example of a general pattern of reactivity. 

The rapid developments in this field make a comprehensive review impractical hence, this report will concentrate on recent developments in technique that are likely to be used more extensively, potential problems in interpretation of dynamic NMR spectra, and observations that establish general patterns of rearrangement or conflict with currently accepted mechanisms. 

We thus have the general pattern of a large and growing body of primary literature making necessary the existence of comprehensive secondary services, and a growing body of review literature. This is the basic structure of the literature from which information may be retrieved.
